Allow list of IAM roles to access the Kubernetes cluster (AWS)

following the discussion on https://discuss.qovery.com/t/how-to-connect-to-aws-eks-using-iam-role/3472/9, it would be helpful to specify in the cluster settings one or more IAM roles that will be enabled to access the Kubernetes cluster (similar to what it is done with IAM users via the Admin group)

As of now, the only solution is to modify the manually aws-auth configuration to enable them.
